Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roof base material used for waterproofing rainwater from roof tiles, which is laid on a base plate.

[0002]

[Prior art]

 The roofing base material, which is laid on the base plate and used for waterproofing rainwater from roof tiles, is waterproof to rainwater, prevents water leakage from the gap between nails and nail holes such as tacker nails, and has strength against the impact of the tacker during construction. Anti-slip performance is required for the base plate, and it is expected to provide a roofing base material that avoids the trouble of slipping during the stepping construction.

[0003]

[Problems to be solved by the device]

 This invention was made under such a background. The first purpose is to maintain the waterproof property against rainwater, and to prevent leakage of water from the gap between the nail and the nail hole even when fixing it with a tacker nail during construction. The purpose is to provide a roof base material that prevents the damage to the impact of the tucker, and does not slip even when walking on the roof base material laid on the base plate during construction.

[0004]

[Means for Solving the Problems]

 The roofing base material according to claim 1 of the present invention comprises a waterproof sheet (1) made of a thermoplastic resin, a non-woven fabric (6) having the waterproof sheet (1) fused and an adhesive to the non-woven fabric (6). And a backing sheet (5) impregnated with a water-resistant resin (7). The roofing base material according to claim 2 of the present invention comprises a convex ridge that crosses the surface of the waterproof sheet (1). (2) is formed by the coating film (3), and the partially exposed mineral particles (4) are fixed to the ridges (2).

[0005]

[Action]

 The roofing base material according to claim 1 of the present invention uses a waterproof sheet (1) made of a thermoplastic resin to prevent water from the roofing material such as roof tiles from reaching the base plate, and penetrates the backing sheet (5). By attaching the adhesive resin (7) constituting the backing sheet (5) to the nails, water leakage from the gap between the nail and the nail hole is prevented, and the waterproof sheet (1) made of a thermoplastic resin is provided. Since the waterproof sheet (1) is fused to the non-woven fabric (6) constituting the backing sheet (5), the waterproof sheet (1) is strong against the impact of the tucker and is not damaged.

In the roof substrate according to claim 2 of the present invention, a ridge (2) which is crossed is formed by a coating film (3) on the surface of the waterproof sheet (1), and the ridge (2) is formed. Since partly exposed mineral particles (4) are settled in (), even when walking on the ground material under the roof laid on the ground plate during construction, it does not slip.

Hereinafter, embodiments of the present invention will be described in detail.

【Example】

 1 and 2 are a sectional view and a perspective view of a roof base material according to an embodiment of the present invention.

As shown in the figure, the roof substrate according to the embodiment of the present invention includes a waterproof sheet (1) made of a thermoplastic resin. This waterproof sheet (1) is limited to thermoplastic synthetic resin in that flexibility is required. For example, a thin sheet formed by calendering vinyl chloride resin, polyethylene, or polypropylene is used. This waterproof sheet (1) prevents the flooding from roofing materials such as roof tiles from reaching the base plate.

On the surface of the waterproof sheet (1), a ridge (2) crossing vertically and horizontally is formed by a coating film (3), and a step is formed between the surface of the waterproof sheet (1) and the ridge (2). A rough surface is formed. Mineral particles (4) partially exposed are fixed to the ridges (2) forming the rough surface, and the ridges (2) are roughened. Therefore, the ridges (2) and the mineral particles (4) fixed to the ridges (2) prevent slipping even when stepping on the surface of the waterproof sheet (1). The coating film (3) is applied by applying a coating material containing a thermoplastic resin as a main component for maintaining the flexibility of the waterproof sheet (1). For example, a vinyl chloride-based or acrylic resin-based coating is used. Aqueous emulsions are preferred. Further, as the mineral particles (4), inorganic substances such as silica, iron oxide, alumina and glass are used.

Further, in the roof substrate according to the embodiment of the present invention, the backing sheet (5) is integrally formed on the back surface of the waterproof sheet (1). That is, the backing sheet (5) is composed of a nonwoven fabric (6) having the waterproof sheet (1) fused and an adhesive resin (7) impregnated in the nonwoven fabric (6). As the non-woven fabric (6), non-woven fabrics made of various synthetic fibers such as polyester and polypropylene fibers are applied, and as the adhesive resin (7), in addition to polyacrylonitrile, polybutadiene, polyvinyl chloride, etc., tar, asphalt, etc. Applied. Here, since the nonwoven fabric (6) enhances the mechanical strength of the waterproof sheet (1) fused to the nonwoven fabric (6), the strength of the tacker against impact during construction is also strong to prevent breakage. The adhesive resin impregnated in 6) has a remarkable effect in preventing water from seeping through the gap between the nail hole and the nail because the adhesive resin (7) that constitutes the backing sheet (5) adheres to the nail. .

[0012]

[Effect of device]

 The roofing base material according to claim 1 of the present invention maintains waterproofness against rainwater, prevents water leakage from the gap between the nails and the nail holes, and prevents damage to the impact of the tucker. Such a roofing base material does not slip even when walking on the roofing base material laid on the base plate during construction.
